3. The 4-way valve is out of order
3. Check the voltage in the electrical wiring to
the 4-way valve. If the problem persist, have
the heat pump checked by a refrigeration
technician.
Problem
The heat pump doesn’t work
Observation:
The serene does not light up and a compressor doesn’t make a sound.
Possible cause
Solution
1. Wrong setting of parameters
1. Check the set parameters and adjust them
(setting just above the capacity of the heat pump)
2. Pressure switch out of order
2. Check operation of the pressure switch turning
off the filter pump and restarting it, If the pump
doesn’t react to this, the pressure switch must be
adjusted or replaced.
3. Electrical failure
3. Contact your installer
Problem
Water leak
Observation:
There’s an amount of water under the heat pump
Possible cause
Solution
1. Insufficient air inflow
1. No action required
2. Water leak
2. Try to localize the leak and check for the presence
of chlorine in the water. If that is the case, the heat
pump must be temporarily replaced during repair.
Problem
Abnormal amount of ice formed on the evaporator
Observation:
The evaporator is for the most part covered in ice
Possible cause
Solution
1. Insufficient air inflow
1. Check the location of the heat pump and remove
any dirt that could be present on the evaporator
2. High water temperature
2. If the pool water is already quite hot (warmer than
29), the probability of ice formation increase.
Lowering the set temperature is a possible option
3. Incorrect setting of automatic defrost
control
3. Check the setting of the defrosting function
together with your installer
4. The 4-way valve is out of order
4. Check the voltage in the electrical wiring to the
4way valve. If electric potential is measured, replace
the coil. If the problem persists, have the heat pump
checked by a refrigeration technician
5. Not enough refrigerant
5. Have the heat pump checked by a refrigeration
technician.
